    I have a mid 2011 iMac with a 2.5 ghz quad-core Intel Core i5... Looking to buy a new one to replace my loyal 2011 I find the new iMacs come with a 2.3GHz dual‑core Intel Core i5. I know there are faster ones but bottom end to bottom end would it be possible that my current processor is faster than the new one?

    The Kaby lake dual-core is about 20-30% faster than the Sandy bridge quad-core. However, I would probably go for quad-core to see substantial improvement.
